36-Item Short Form Survey (SF-36) calculator

About the score:

Originally published in 1992 in Medical Care, the 36-item Short Form Health Survey (SF-36) is a measure of health-related quality-of-life. It is a subset of questions from longer instruments that were used in the Medical Outcomes Study. There have been a variety of iterations of this tool, and the version presented here is more specifically known as the RAND SF-36

The SF-36, as described in the name, is a 36-item patient-reported questionnaire that covers eight health domains: physical functioning (10 items), bodily pain (2 items), role limitations due to physical health problems (4 items), role limitations due to personal or emotional problems (4 items), emotional well-being (5 items), social functioning (2 items), energy/fatigue (4 items), and general health perceptions (5 items). Scores for each domain range from 0 to 100, with a higher score defining a more favorable health state.
